I wanted to book two air tickets to Las Vegas and return, to spend ten days including New Year Eve with our friends living there. It was October so I feared it might be very expensive so close to such high demand dates. CheapOair offered me reasonable pricse for very convenient and direct flights, I got what I wanted in a very short time, with minimum efforts.
I usually search several sites when I try to book air tickets for my vacation. Orbitz came up with the best price a few times and I had no trouble booking the flights.
